Reported distribution of chronic wasting disease (CWD) in North America. Die Diagnose erfolgt durch eine mikroskopische Untersuchung von Gewebeproben aus dem Gehirn, in denen die charakteristischen schwammartigen Veränderungen des Nervengewebes nachgewiesen werden können. Sekundär kann es aufgrund der Schäden am Nervensystem auch zu einer Aspirationspneumonie kommen, da die Krankheit den Schluckvorgang stört. Es ist dabei vergleichbar mit BSE bei Rindern, Scrapie bei Schafen und auch Muffelwild oder Creutzfeldt-Jakob beim Menschen. It eats holes into the brains of deer, elk, moose, and reindeer, causing them to starve themselves, drool excessively, feel unquenchable thirst, and die a slow agonizing death.

Chronic Wasting Disease belongs to a group of disease which is known as transmissible spongiform encephalopathies. The second tool called 'Estimation' is for use after sampling for CWD detection has occurred and no positive cases were found. Jim Mimiaga/The Journal . Betroffene Tiere müssen gekeult werden. Natural infection causing CWD af… Chronic wasting disease, or CWD, is a fatal neurological disease that affects cervids, including white-tailed deer. Chronic wasting can lead to long-term population declines if left unchecked and it can destroy farm-raised game animal herds. In addition to research, the NWHC also conducts numerous communications and outreach activities and products, such as fact sheets, briefings, media interviews, and presentations, on both a national and international scale. All mammals produce normal prions that are used by cells, then degraded and eliminated, or recycled, within the body.

Die natürliche Infektion erfolgt mutmaßlich auf oralem Weg; das veränderte Protein wird sodann vermutlich durch die Peyer-Plaques des darmassoziierten Immunsystems aufgenommen und wandert wohl über den Nervus vagus ins Gehirn, wo es akkumuliert und nach und nach zur Ausbildung der spongiformen Hirnveränderungen führt.

Deer infected with CWD show the presence of abnormally shaped proteins called “prions,” which cause healthy proteins to convert into diseased proteins. It has been found in some areas of North America, including Canada and the United States, Norway and South Korea.

Bei in Gefangenschaft lebenden Hirschherden wurde die Krankheit auch in anderen westlichen Staaten der USA sowie im westlichen Kanada festgestellt. Efforts will continue to focus on improving diagnostic testing platforms in collaboration with the U.S. Food and Drug Administration, providing surveillance and modeling technical assistance to a long-term CWD study carried out by the Wisconsin Department of Natural Resources, developing modeling techniques for predicting CWD growth within free-ranging cervid populations and forecasting disease spread in regions of interest, and continued identification and development of novel anti-prion compounds and processes to disrupt disease transmission cycles.
